Understanding Concepts
13. Acceleration = 0 km/s (velocity is constant)
14. Equal in length, opposite in direction
15. Doubled.
16. Speed at a specific instance of time.
17. Straight line
18. 1 meter to the left.
Understanding Concepts
19. 6.4 km/h
20. 990 m
21. 2.0 m/s upstream
22. Acceleration is zero
23. Acceleration is not constant
24. Acceleration is due to a change in velocity direction.
Critical Thinking
25. It would appear to drop down vertically.
26. Measure the track, time a loop around the track,
calculate the speed.
27. Yes. Each measurements produces a velocity of .83
m/s
28. 1400 m/s
Math Skills / Concepts in Action
29. Starting from rest, the person walked 15 m at a
constant rate for 10 seconds then rested for another 10
sec.
30. 1.5 m/s
32. 600 m/s which is less than the velocity in #28
33. A falling ball has a constant acceleration = 9.8 m/s2.
The bouncing ball has a changing acceleration.
34. 5 km/h
